VAPORIZER FOR. DISINFECTANTS.

To all whom 'it may concern;

Be it known that I, CHARLES CARROLL Lrnx'rnnns, a citizen ot' the United States of America, residing at Leytonstone, England, have invented certain new and useful Improvements in Vaporizers for Disinfectants, of which the following is a specification.

This invention relates to that class of apparatus for disinfecting, deodorizing, perfumiug or otherwise treating air in rooms or other places, in which the disinfecting liquid or perfume is contained in a receiver and is conveyed through an outlet to a shallow vessel or tray in proportion to the evaporation taking place, the vessel being provided with a wick or iiannel, whichis saturated by the liquid to insure a large surface for the air to act upon.

The object of this invention is to construct an improved form of apparatus, easier of construction, and more eilicient in action, for disinfecting, deodorizing, perfuming or otherwise treating air in rooms or other places.

My invention will be clearly understood from the following description aided by the accompanying drawings in' which i Figure l is a longitudinal sectional elevation of a complete ap aratus for hanging on a wall. Fig. 2 is a side elevation of same.

For the purpose of my invention I emplo three vessels l, 2, and 3, connected togetlier by screw, bayonet joint or other means, and these vessels I arrange in a superposed manner. The lower vessel 1 is of glass, earthenware or like'non-porous material, the center vessel or tubular connection 2 is of open meshed or openworked material or character, and the upper vessel 3 is of glass, earthenware or like non-porous material, having a depending tube a which passes through the center vessel 2 into the ower vessel'l. Positioned in the lower and central vessels, and surrounding the tube is a porous tube 5, plaited wick or other like tube, held in position by the glass' or like tube 4, depending from the upper vessel 3, or standing in the lower vessel 1, and held by the screw thread 6 of the tubular connection 2.

The tube 4 projecting from the upper vessel is provided with a valved rod 7, soV that after filling the up er vessel 3, the water or liquid contained tierein can be Asealed for the purpose hereinafter describedw y,

pulp tube and support, the tube from the upper vessel may be surrounded with a tube or' wood, cork, or other porous material capable of holding liquid by capillary action.

In action I first detach the three vessels, l, 2, and 3 from one another, I then till the lower vessel l with a iiuid capable of disinfecting, deodorizing, ozonizing, perfuming or otherwise acting upon the air, and I then connect the center vessel 2 to the lower vessel l by a bayonet joint 8 or other means of fasteningand place in the porous wood pulp tube, plaited wick or the like, this reaching to the bottom'of the lower Vessel and sticking up some of the liquid and becoming saturated. I then take the top vessel 3 and move the valve 9 on the rod 7' from its seating l() (if on) and fill the vessel 3 with the liquid. I then pull the valve 9 on its seating l0 to prevent the liquid running out of the tube 4. The tube liis now inserted into the center 2 and lower vessel l, and the top vessel 3 is connectedl to the center vessel by its screw ll, engaging the' screw '(3 of the center vessel or otherwise, and in so doing the valve rod 7 will be lifted and move the valve 9 from its seating 10 so that some of the liquid in the top cham er 3 runs down and fills the tube It, and this being sealed by the water in the lower vessel l, and there being no vent in the top chamber 3, will remain in the tube 4 and top chamber 3. The air circulates through the openworked or perforated vessel or tubular connection 2, and comin in contact with the wood pulp tube 5, p aited tube or the like, parta es of odor and oils of the deodorizing, disinfecting or perfuming avent, and disseminates same through and atbout the room. As the evaporation of the liquid in the tube 5 takes place, the liquid from the lower vessel l is sucked up the tube 5 and restablishes the moisture by capillary action, and ,when the liquid in the lower vessel l has reached a depth suicient to break the seal of the tube 4, sufficient liquid from the upper vessel 3 will pass into the lower vessel l to compensate for that taken out and re establish the sealing of the-pipe e to stop further sup ly, so that the feed from the upper' chamlier 3 to the lower chamber 1 is automatic and only takes place when the liquidin the lower chamber 1 has lowered sufficiently.

I prefer to angle the bottom of the tube 4 as at 12 from the upper Vessel 3, so that Patented Nov. 16, i909.

the automatic supply to the lovvei` vessel i is gradual and not of large volume.

The tube 5 may be peiioi'ated to viiisni'e the' air passing through same so as to better pai'tiike of the odoi` which ernzmates from the liquor held by the tube 5 in the vessel i2.

The apparatus may be connected to e bracket 13 foi' hanging to :L wall, or muy be used as on a table or otherwise.

What I do claim as my invention, and de sire to Secure by Letters Patent is2- An apparatus for disinfeeting oi' deodorizing purposes, Comprising three supeposed connected vessels, the top vessel being provided with a valve seat and having a tube depending through the second 'vessel and into the oottom vessel, an absorbent tube In testimony' ivliti'eofll-haveheieunto set
